According to CNBC, South Korea is taking a cautious approach to the long-planned Alaska liquefied natural gas project even after U.S. President Donald Trump said it was part of Seoul's $200 billion investment package in the United States. Trump said the two countries had agreed to work on the $50 billion project, but South Korean President Lee Jae Myung said participation would depend on financial viability and legal compliance. The Alaska LNG project would move gas through an approximately 800-mile pipeline from Prudhoe Bay to an LNG facility in Nikiski and is expected to produce 20 million metric tons of LNG a year, with estimated costs of $44.5 billion to $54.5 billion. South Korean buyers are weighing the project's long pipeline, potential cost overruns, long construction timeline and take-or-pay contracts that could last 20 years or more. POSCO International has a non-binding agreement for potential purchases of 1 million metric tons of LNG annually for 20 years and steel supply for the pipeline.
